Update vendor payment
From Protemos Wiki
Press "Update" to go to the Update payment details page:
Here you can change the following payment details: "Payment method", "Paid at", "Currency", "Amount", and "Note":
You cannot change the vendor, so if the vendor is wrong, the only way out is to delete the payment and create a new one.
If you need to unlink or link invoices to this payment, it can be done on the Vendor payment page.
